The purpose of a muffler is to decrease the amount of noise emitted by the exhaust of an internal combustion engine and your exhaust is tasked with removing harmful fumes and emissions from your vehicle. Both these components are referred to as the “Exhaust System”. Exhaust systems are crucial to your safety, as a defective exhaust system can cause potentially fatal gases, such as carbon monoxide to leak into the cabin of your vehicle. The catalytic converter, which is part of the exhaust system, helps convert dangerous gases to mostly harmless ones that do less damage to the environment. Finally, your exhaust system is responsible for reducing the temperature of emissions – protecting other vehicle components from being damaged. For these reasons, regular inspections of your exhaust system and muffler are critical.
